FEM Simulation of Subintimal Angioplasty for the Treatment of Chronic Total Occlusions

Figure 1

Scheme of subintimal angioplasty balloon inflation. (a) Guidewire is advanced between the intima and media layers, creating a false lumen (subintimal space). (b) Once the tip of the catheter has passed through the second end of the CTO, the guidewire reenters the artery by means of devices specifically developed. (c) Balloon inflation.
